Abstract

Bismuth oxide synthesis using hydrothermal method has been conducted. This study aims to examine the effect of the hydrothermal reaction time on product characteristics and photocatalytic activity in degrading methyl orange dye. Bismuth oxide synthesis was initiated by dissolving bismuth nitrate pentahydrate (Bi(NO3)3.5H2O) and Na2SO4 in a distilled water and added NaOH gradually. The solution formed was transferred into a Teflon-lined autoclave and heated at 120 °C with time variations of 8–16 h. The formation of bismuth oxide was indicated by the vibrations of the Bi−O−Bi and Bi−O groups and the crystal structure consisting of a-Bi2O3, β-Bi2O3, and g-Bi2O3. In addition, the highest photocatalytic activity can be examined through several factors, such as: content of Bi−O−Bi and Bi−OH groups, crystal structure, band gap values, morphology, and surface area, acquired as a result of the effect of hydrothermal reaction time.

类炸薯条氧化铋:理化性质、电导率和光催化活性

采用水热法合成了氧化铋。研究了水热反应时间对降解甲基橙染料的产物特性和光催化活性的影响。在蒸馏水中溶解五水硝酸铋(Bi(NO3)3.5H2O)和Na2SO4，并逐渐加入NaOH，引发氧化铋的合成。将形成的溶液转移到铁氟龙热压釜中，在120℃下加热8-16 h。通过Bi−O−Bi和Bi−O基团的振动以及由a- bi2o3、β-Bi2O3和g-Bi2O3组成的晶体结构来表征氧化铋的形成。此外，通过水热反应时间的影响，可以通过Bi−O−Bi和Bi−OH基团的含量、晶体结构、带隙值、形貌和表面积等因素来考察最高的光催化活性。版权所有©2021作者，BCREC集团出版。这是一篇基于CC BY-SA许可(https://creativecommons.org/licenses/by-sa/4.0)的开放获取文章。
